Veritas Firesystem

VERITAS filesystem is a journaling filesystem. This means transactions are logged so that if a failure occurs,
the transactions can be rolled forward. This prevents filesystem corruption as well as allows the system to do a
filesystem check (fsck) faster.

Normally, at boot-up after a crash, a system needs to manually check the integrity of all the filesystems. With
VERITAS, it checks the journalled logs, and then comes up. This can save 30-60 minutes on large filesystems.

Generally, maintanence for VERITAS file system is often done with VERITAS Volume Manager.
